Electro-hydraulic servo valve suitable for large g value acceleration environment

2013 
The invention discloses an electro-hydraulic servo valve suitable for a large g value acceleration environment. The electro-hydraulic servo valve comprises a servo valve body and a valve block. The servo valve body comprises a first servo valve body and a second servo valve body. The first servo valve body and the second servo valve body are of the same structure and installed on the valve block side by side. The axial direction of valve cores is the same as the centrifugal acceleration direction of a centrifugal machine. The S port of the first servo valve body is communicated with the S port of the second servo valve body through a channel in the valve block. Through the direct drive mode and the connection mode of the first servo valve body and the second servo valve body, it is guaranteed that the valve core of the first servo valve body and the valve core of the second servo valve body are still located in the neutral position under a centrifugal field, centrifugal force is compensated, high-frequency-response servo control can be provided under the large g value centrifugal field, and the defect that a common servo valve is easily affected by centrifugal acceleration or can not work under the centrifugal environment is overcome; a direct drive large-flow slide valve is adopted, links are few, frequency characteristics are high, and wave form distortion is small.
